Dec 14, 2015 Here is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 ...

MoreThe Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).

MoreDescription Bond’s Abrasion Test AKA Allis Chalmers Abrasion Test. Bond’s abrasion test consists of a hardened Cr-Ni-Mo alloy steel paddle (hardness 500 Brinell). 7.62 cm X 2.54 cm X 0.64 cm with 2.54 cm of its length silling inside a rotor. 11.43 cm diameter. The rotor is covered by a concentric steel drum 11.43 cm in length and 30.54 cm in diameter.

MoreThe Bond Index conforming rod charge consists of: 6 rods of 1.25“ diameter and 21“ length. 2 rods of 1.75“ diameter and 21“ length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

MoreThe ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
